1. The document summarizes research by CRC on predicting coverage of FM-IBOC (in-band on-channel digital radio) systems using their CRC-COVLAB software. 2. Field measurement data from tests done by NPR and iBiquity on actual FM-IBOC broadcasts were used to validate the accuracy of the CRC-COVLAB FM-IBOC prediction module. 3. Results showed good correlation between predictions and measurements, with some minor discrepancies in one location, demonstrating the high accuracy of the CRC-COVLAB tool for FM-IBOC planning and interference analysis.
